Travellers expressed their frustration on social media. "Moral of the story, if you don't have to travel and have a low patience threshold, don't fly," said one.Sunday marked the 40th day of the record shutdown and the third day of flights being reduced at airports nationwide, after the Trump administration ordered reductions to ease strain on air traffic controllers working without pay."We're going to see air traffic controllers, very few of them coming to work, which means you'll have a few flights taking off and landing," Duffy told Fox News Sunday."You're going to have massive disruption (and) a lot of angry Americans."Duffy sought to blame Democrats for the high-stakes political standoff, but Senator Adam Schiff said Republicans were rejecting a "reasonable" compromise deal to end the shutdown."And the result from the Senate Republicans was 'no', from the House Republicans 'we are staying on vacation', and from the president 'I'm going out to play golf', and that's where we are while people are hurting," Schiff said.When asked whether Democrats would turn around and vote with Republicans, Schiff, a California Democrat, indicated that the issue of healthcare subsidies remained a sticking point in negotiations."No, I certainly hope it isn't going to happen if millions of people are going to retain their health coverage and not have to pay these exorbitant premium increases," Schiff said on ABC's This Week with George Stephanopoulos."We need to end this. We proposed something, I think very reasonable. It was a compromise. "Certainly wasn't everything I want, which is a permanent extension of the tax credits," he said, urging Republicans to allow "more time to work on this and reopen the government."
